Y-Formalism and Curved Beta-Gamma Systems
arXiv:0803.0236 · doi:10.1016/j.nuclphysb.2008.04.016
Abstract
We adopt the Y-formalism to study beta-gamma systems on hypersurfaces. We compute the operator product expansions of gauge-invariant currents and we discuss some applications of the Y-formalism to model on Calabi-Yau spaces.
